CLR SQL 程序集:获取字节流? [英] CLR SQL Assembly: Get the Bytestream?

问题描述

我有一个想要部署的 SQL CLR dll，但我发现您可以将字节流/varbinary_literal/varbinary_expression/assembly 位嵌入到文本文件中，以避开打包 DLL 并确保其可访问的麻烦创建汇编命令.

I have a SQL CLR dll I want to deploy, but have found you can embed the byte stream/varbinary_literal/ varbinary_expression/assembly bits into a text file to get around the messy hassle of packaging a DLL and making sure it's accessible for the CREATE ASSEMBLY command.

但我还没有找到如何获得该字节流/varbinary_literal/varbinary_expression/assembly bits 值.我没有找到任何一致的术语，以及我在使用 Load() 时不断发现的内容.

But what I have yet to find is how to get that byte stream/varbinary_literal/ varbinary_expression/assembly bits value. I haven't found any consistent terminology, and what I keep finding in using Load().

推荐答案

这只是 dll 的十六进制表示.这一点应该可以解决问题:

It's just a hex representation of the dll. This bit should do the trick:

    static string GetHexString(string assemblyPath)
    {
        if (!Path.IsPathRooted(assemblyPath))
            assemblyPath = Path.Combine(Environment.CurrentDirectory, assemblyPath);

        StringBuilder builder = new StringBuilder();
        builder.Append("0x");

        using (FileStream stream = new FileStream(assemblyPath,
              FileMode.Open, FileAccess.Read, FileShare.Read))
        {
            int currentByte = stream.ReadByte();
            while (currentByte > -1)
            {
                builder.Append(currentByte.ToString("X2", CultureInfo.InvariantCulture));
                currentByte = stream.ReadByte();
            }
        }

        return builder.ToString();
    }

你应该像这样使用结果字符串:

You should use the resulting string like so:

string hexString = GetHexString(assemblyPath);
string sql = "CREATE ASSEMBLY [" + assemblyName + "] FROM " + hexString + 
             " WITH PERMISSION_SET = " + somePermissionSet;
